Tornado watch issued for seven NW Missouri counties

A tornado watch has been issued for parts of Iowa, Nebraska and northwest Missouri.

The National Weather Service’s Storm Prediction Center issued the watch Tuesday afternoon and it is expected to remain in effect until 7 p.m.

The counties under the watch include Andrew, Atchison, Dekalb, Gentry, Holt, Nodaway and Worth in Missouri.

The primary threats include the possibility of intense tornadoes, large hail and widespread damaging winds with some gusts up to 90 mph.

A tornado watch means conditions are favorable for tornadoes and severe thunderstorms in and close to the watch areas.

The powerful storm complex is expected to form over Nebraska, Iowa and northern Missouri and could bring severe weather to Kansas City area Tuesday evening.

The areas most likely to see these storms are north of the U.S. 36 corridor — from St. Joseph to Macon, Mo. However, there is a chance the storms could spread fsrther south toward Interstate 70, where the environment will be favorable for severe storms and heavy rainfall, according to the National Weather Service in Pleasant Hill, Mo.

Scattered thunderstorms are expected to start forming over eastern Kansas and western Missouri early Tuesday afternoon. These storms might quickly produce large hail and damaging winds, according to the National Weather Service.

By mid-afternoon, widespread thunderstorms are expected to develop over South Dakota, Nebraska and northern Kansas. Those storms are expected to become a strong thunderstorm complex and move across southern Iowa and northern Missouri, according to the National Weather Service.

Early risks will be large hail, damaging winds and a few tornadoes. Later, risks for damaging wind and flash flooding will increase. The heaviest rainfall is expected across northern Missouri and southern Iowa. This could lead to flash flooding across northern Missouri Tuesday night and minor river flooding later this week.

Several rounds of strong to severe thunderstorms are possible Thursday into the weekend.

Heavy rain is possible, especially Friday and Saturday afternoon and night, which could to lead to an elevated flooding risk later this week, according to the National Weather Service.
